Madrid’s Sierra Norte Set to Benefit from Expanded Fiber Optic Network
Residents of the Sierra Norte region of Madrid are poised to experience significantly improved internet connectivity thanks to a novel initiative by the Comunidad de Madrid. The project, announced on March 13, 2026, aims to bridge the digital divide for over 25,000 residents in 42 municipalities historically hampered by challenging terrain and sparse population density. The expansion will see the installation of 100 kilometers of new fiber optic cabling, bolstering existing infrastructure and bringing reliable high-speed internet access to areas previously underserved. This investment underscores a commitment to territorial equality, ensuring that rural communities have the same opportunities as their urban counterparts in an increasingly digital world.
The initiative was unveiled following a meeting between the Comunidad de Madrid’s Digitalization Counselor, Miguel López-Valverde, and the mayors of the Sierra Norte municipalities, held in La Cabrera on March 13, 2026. The meeting served as a platform to detail the ongoing and planned projects designed to enhance connectivity in towns with populations under 20,000. Beyond simply expanding the network, the focus is on improving stability and ensuring long-term continuity of service – issues that have long plagued residents of the region, resulting in frequent outages and unreliable connections. This commitment to robust infrastructure is crucial for supporting remote work, education, and access to essential online services.
The expansion builds upon previous work completed in the southwestern region of Madrid, demonstrating a phased approach to improving digital infrastructure across the Comunidad de Madrid. The project is being carried out by the Office for Connectivity Promotion within the Department of Digitalization, in collaboration with telecommunications operator Movistar. This partnership leverages the expertise of a major provider to accelerate the deployment of fiber optic technology and ensure a high standard of service. The collaboration highlights a public-private approach to addressing the challenges of rural connectivity.
100 Kilometers of Fiber Optic Cable to Enhance Connectivity
The core of the initiative is the installation of 100 kilometers of new fiber optic cable in several municipalities throughout the northern region. Work is already underway in Alameda del Valle, Rascafría, Lozoya, Buitrago del Lozoya, and Villavieja del Lozoya. This targeted deployment aims to address specific connectivity gaps and provide a significant boost to internet speeds and reliability for residents and businesses in these areas. The new cabling will supplement existing infrastructure, creating a more resilient and robust network capable of supporting the growing demands of modern digital life.
Counselor López-Valverde emphasized that the project isn’t solely about extending the network’s reach, but also about enhancing its stability and ensuring its long-term viability. Frequent service interruptions, slow speeds, and unreliable connections have been persistent challenges for residents in these areas, hindering economic development and limiting access to essential services. The new fiber optic infrastructure is designed to mitigate these issues, providing a more consistent and dependable internet experience.
The benefits of this infrastructure upgrade are expected to extend to more than 25,000 residents in the region. Improved connectivity will facilitate remote work opportunities, enhance access to online education and healthcare services, and support local businesses. The project represents a significant investment in the future of the Sierra Norte, empowering residents and fostering economic growth.
Beyond Connectivity: Modernizing Municipal Management
The Comunidad de Madrid’s commitment to digital inclusion extends beyond residential connectivity. The regional government is also providing technological equipment to 142 municipalities with populations under 20,000, aiming to modernize municipal management and improve citizen services. This initiative will equip local governments with the tools they need to streamline administrative processes, enhance public services, and improve communication with residents. The modernization effort is expected to improve efficiency and transparency in local government operations.
Specifically, the initiative includes support for the digitization of municipal archives, the creation of electronic headquarters (sede electrónica) to expedite administrative procedures, and the implementation of a Digital Shield to enhance cybersecurity for all town halls. These measures will empower local governments to deliver more efficient and accessible services to their constituents. The Digital Shield, in particular, is a critical component of the initiative, protecting sensitive data and ensuring the integrity of municipal systems.
Expanding 5G Coverage Across the Region
In addition to the fiber optic expansion, the Comunidad de Madrid has been actively working to broaden 5G coverage, particularly in rural areas and locations with limited internet access. As of March 2026, 5G technology is available to 99.6% of the region’s population. This significant achievement demonstrates the government’s commitment to ensuring that all residents have access to the latest wireless technology. The expansion of 5G coverage is crucial for supporting a wide range of applications, including smart agriculture, remote healthcare, and connected vehicles.
The remaining 0.4% of the population without 5G access remains a priority, and the regional government has set a goal of achieving full connectivity before the end of the current legislative term. This ambitious target, if realized, would position Madrid as a leader in digital coverage within Europe. The ongoing efforts to expand 5G coverage are a testament to the government’s commitment to bridging the digital divide and ensuring that all residents can benefit from the opportunities offered by advanced wireless technology.
Hoy hemos reunido en La Cabrera a representantes de los 42 municipios de la Mancomunidad de la Sierra Norte para presentar los servicios que desde la Consejería de #Digitalización de la Comunidad de Madrid hemos puesto a su disposición. ➡️ https://t.co/o8keWq9w9q

As Counselor López-Valverde stated, the overarching goal is to “guarantee a quality service for all homes, regardless of where they are located.” This sentiment underscores the government’s commitment to equitable access to digital infrastructure and services. The initiatives outlined above represent a comprehensive strategy to achieve this goal, addressing both the physical infrastructure and the digital skills needed to thrive in the 21st century.
For residents of Rascafría, Lozoya, and other municipalities in the Sierra Norte, these projects translate into tangible benefits. The ability to work from home without interruption, participate in seamless video calls, access online government services without traveling to the city, and enjoy streaming and communication services are all within reach. These improvements will not only enhance the quality of life for residents but also stimulate economic activity and attract new investment to the region.
The digital divide between rural and urban areas has been a persistent challenge across Spain. In the Comunidad de Madrid, these measures aim to close that gap, ensuring that residents of all communities have equal access to the opportunities offered by the digital economy. The ongoing investment in infrastructure and digital skills development is a critical step towards creating a more inclusive and prosperous future for all.
The next update on the progress of the fiber optic rollout is expected in June 2026, when the Comunidad de Madrid will release a report detailing the completion of the initial phase of the project. Residents and stakeholders are encouraged to share their feedback and experiences with the new infrastructure through their local town halls and the Comunidad de Madrid’s digital services portal.
